Bullying behaviour in schools, socioeconomic position and psychiatric morbidity: a cross-sectional study in late adolescents in Greece

Exploring Aggressive Behaviors in Greek Secondary Schools: Prevalence, Sociodemographic Factors, and Comparative Analysis with Elementary School Students

The main objectives of this study are to determine the prevalence of bullying in Greek secondary schools and detect the possible characteristics of bullies' profiles in Greek school settings. A structured questionnaire was given to one hundred ninety-two (n = 192) educators at Greek junior high schools in urban and rural areas. The educators were asked to report the frequencies and forms of aggressive behavior observed during the 2022-2023 school year, the bullies' sociodemographic characteristics, and ways of dealing with bullying episodes. The data are presented, after conducting statistical analyses, in comparison with data for elementary school students. The results revealed that higher rates of bullying were reported compared with elementary school children. Moreover, according to teachers' observations, aggressive behavior is independent of a pupil's diagnosis, but specific types are correlated significantly with a pupil's gender, nationality, low academic performance, and popularity. Factor analysis showed two main factors of aggression types, where common points and differences with elementary school students are mentioned. Implementations for the prevention of school bullying are discussed.

Bullying victimization among adolescents: Prevalence, associated factors and correlation with mental health outcomes

INTRODUCTION

Knowledge of the risk factors of bullying victimization in adolescents is crucial for the implementation of preventive measures. This study aimed to determine the prevalence and associated factors of bullying victimization and to identify its correlation with mental health outcomes among middle school students in Tunisia.

METHODS

A cross-sectional study was conducted using a multi-stage cluster sampling technique to recruit a sample of 1111 students from 10 middle schools in El kef (Tunisia). The revised Olweus Bully/Victim Questionnaire was used to assess the prevalence and types of bullying victimization and the perceived efforts of others to counteract bullying. The Strengths and Difficulties Questionnaire (SDQ) was used for screening emotional and behavioral problems. Multivariate logistic regression analysis was conducted to determine associated factors of bullying victimization. Additionally, we tested whether emotional and behavioral problems were present for bullying victims.

RESULTS

The findings reported that 45.8% (95%CI = 45.5-46.0), of the total number of participants experienced school bullying victimization. Multivariate logistic regression analysis, revealed that repeating a grade (OR = 1.82, 95%CI = 1.31-2.54), having a working father (OR = 17.68; 95%CI = 2.29-136,15), and having a working mother (OR = 1.88, 95%CI = 1.39-2.53) were the factors significantly associated with bullying victimization. Nevertheless, a higher mother's educational level (OR = 0.76, 95%CI = 0.67-0.88) was a protective factor against bullying victimization. The self-reported SDQ revealed that the total difficulties score was significantly higher among victims (17.46 ± 5.30 vs. 20.86 ± 5.06, p<0.01).

CONCLUSIONS

This study showed that the prevalence of bullying in middle schools was high and it significantly led to mental health problems. National policies for bullying prevention within schools are potentially needed. Improving students' problem-solving and soft skills is also essential.

Prevalence of Aggressive Behavior in Greek Elementary School Settings from Teachers' Perspectives

The present study aims to estimate the prevalence of bullying in Greek elementary schools and to study the risk factors that lead to bullying episodes. A structured questionnaire was given to 221 teachers of elementary schools and 71 kindergarten teachers from urban and rural Greek schools. They were asked to note the forms and the frequency of aggressive behaviors that they had witnessed during the school years 2020-2021 and 2021-2022, as well as the sociodemographic characteristics of the aggressive children involved. Statistical analyses of the data were conducted, and the obtained results show that specific forms of aggression are significantly correlated with gender and low academic performance. In addition, there is no form of aggressive behavior that is associated with the perpetrator's age, nationality or family status. Further, the results of the factor analysis revealed four dominant factors in the aggressive behavior observed by teachers. The forms of bullying and the prevailing factors of aggressive behavior that dominate in Greek school settings are reported in the present study. Furthermore, a novel evaluation tool for teachers could potentially be developed based on the results of the present study.

Household Dysfunction Is Associated With Bullying Behavior in 10-year-old Children: Do Socioeconomic Circumstances Matter?

This study measured the prevalence of bullying behavior in 10-year-old children and investigated the effect of the socioeconomic context on the impact of household dysfunction on bullying. We studied 5,338 members of the Portuguese Generation XXI birth cohort. Information on involvement in bullying, socioeconomic characteristics, and household dysfunction was collected by trained interviewers using structured questionnaires. Being a victim of bullying was reported by 14.4% of participants, being a bully by 1.4%, and being a bully-victim by 3.9%. Being a victim or both bully-victim, simultaneously, was more frequent among children from medium-high income families. Also, children from low-income families who reported household substance abuse, witnessed parents' intimate partner violence, and were victims of physical violence, were more frequently victims of bullying; and those who experienced family violence were more frequently involved as bully-victims. Among children from medium-high income families, all these household adversity experiences significantly increased the odds of being victim, bully, or bully-victim. Thus, although children from medium-high income families are less likely to experience adversity at home, when it happens, there is a greater effect on their behavior, suggesting that better socioeconomic circumstances do not seem to act as a protective factor.

Pathways to socioeconomic health differences in Armenian adolescents: The role of bullying perpetration

Bullying perpetration might be an alternative way of hierarchy formation among adolescents. It can potentially compensate for the negative health influences of low socioeconomic status (SES), rewarding this unwanted behavior. This study aimed to investigate the role of bullying perpetration in the relationship between SES and health among Armenian adolescents. A nationally representative sample of 3679 adolescents aged 11–15 years (mean = 13.1, standard deviation = 1.6) participated in the Health Behavior in School-aged Children 2013/14 survey in Armenia. Complex samples multiple logistic regression were used to estimate the associations between two SES measures (family socioeconomic position [SEP] and material well-being) and three health outcomes (perceived health status, psychosocial well-being, and psychosomatic symptoms). Bullying perpetration was not associated with less than good health or low psychosocial well-being (P > 0.05) but increased the odds of reporting high psychosomatic symptoms (P < 0.05). Perpetration did not change the SES-health gradient substantially. However, in stratified analyses, socioeconomic inequalities in health were consistently weaker among perpetrators. The largest observed difference was in the relationship between low family SEP and less than good health (OR = 3.60, 95% CI = 2.77–4.67 vs. OR = 1.80, 95% CI = 1.06–3.04), whereas the smallest difference was in the relationship between low family SEP and high psychosomatic symptoms (OR = 1.27, 95% CI = 1.03–1.56 vs. OR = 1.04, 95% CI = 0.61–1.77). Our findings suggest that bullying perpetration, as an alternative hierarchy, may be looked at as a compensatory but vicious strategy in the face of the negative health influences of low SES in Armenian adolescents. For high-SES adolescents, on the other hand, social, emotional, or psychological problems might contribute to bullying perpetration. Consequently, bullying prevention activities in Armenia should focus on both low and high-SES adolescents, considering SES-specific pathways and mechanisms.

The Association between Participation in Fights and Bullying and the Perception of School, Teachers, and Peers among School-Age Children in Serbia

Participating in physical fighting and bullying can be a cause of severe injury and death among school-age children. Research evidence can support school and health actors' efforts to improve school-age children's development and health capacity for life. The study aims to assess the prevalence of school-age children's participation in fights and bullying in Serbia, and to examine the relevance of students' socio-demographic characteristics and perceptions of school and relations with other students and professors for participation in fights and bullying. A secondary analysis is also performed on the original data of the 2017 HBSC study, which was conducted on 3267 students in a nationally representative sample of primary and high schools in Serbia. We sought to investigate the relationship between eight socio-demographic characteristics and nine school-related perceptions, with two outcome variables: taking part in fights and taking part in bullying, examined by using univariate and multivariate logistic regression. The main results show that 50.8% of boys and 17.1% of girls have taken part in fights, while 17.7% boys and 10.4% of girls have taken part in bullying. Students who felt a large and very large burden of school obligations were 1.43 times more likely to participate in bullying at least once, while they were 1.38 and 2.12 times more likely to participate in multiple fights and 4.04, 1.24, and 2.78 times more likely to participate multiple times in bullying. Multiple participation in fights and in bullying is significantly negatively associated with female gender, younger age years, good and very good perception of family financial status and quality of life, and positive perceptions of school and relations they have with other students and professors. Fights among school-age children are significantly positively associated with living with relatives/legal guardians and poor quality of life. In conclusion, the prevalence of participating in at least one fight/bullying is higher than in multiple fights/bullying. These associations suggest a necessity to enhance the monitoring and control of peer behavior among school-age children. The findings of the study imply key enablers of protection, such as building relationships based on team spirit and work, friendly behavior, empathy, and help, which should be included in the value system of school and family activities in programs to combat fights and bullying in school-age children.

Prevalence of Bullying and its Co-occurrence with Aggression and Mental Health Problems among Greek Adolescents Attending Urban Schools

BACKGROUND

Bullying is one widespread violence type that threatens adolescent's well-being in family, school, and neighborhood. This study aimed to estimate the percentages of the last 12 months bullying behaviors- types among Greek adolescents, and to identify the associations between these behaviors and adolescents' aggression and mental health- behavioral problems.

STUDY DESIGN

A cross-sectional study.

METHODS

The sample consisted of 1934 adolescents, attending the second grade of 45 randomly selected public and private high schools and senior high schools, of the Greater Athens Metropolitan Area. Bullying involvement was examined by four questions, evaluating the occurrence and type of bullying. The Buss and Perry Questionnaire and Strength and Difficulties Questionnaire were administrated in order to estimate adolescents' aggression and mental health-behavioral problems, respectively. Information about adolescents' individual and family characteristics was also collected.

RESULTS

Overall, 18.4% of participants reported bullying involvement at school, as a victim (11.0%), a bully (5.0%), or both (2.4%), while verbal bullying was the most common type. Compared to uninvolved participants, victims were significantly more likely to report emotional symptoms and peer problems, bullies were more likely to report physical aggression, and bully-victims physical aggression, hostility, and lower prosocial behavior.

CONCLUSIONS

Approximately one out of five adolescents were involved in bullying in the past year at school, reporting aggressive behaviors, emotional problems, and/or social difficulties. Further longitudinal research would increase understanding of the mechanisms of bullying involvement and may lead to preventative interventions promoting positive peer interactions in schools.

Structural family factors and bullying at school: a large scale investigation based on a Chinese adolescent sample

Backgrounds

Various family factors have been identified in association with school bullying and the involvement of children and adolescents in bullying behaviors.

Methods

A total of 11,919 participants (female = 6671, mean age = 15) from 22 middle schools in Suzhou City, China completed the questionnaire. The associations between structural family factors (family socio-economic status, living arrangement, number of siblings, whether they were local residents/migrants, had an urban/rural hukou [a household registration system in China], parental and maternal education levels, and other various bullying-related constructs (i.e. bullying witnessing, bullying involvement, bystander intervention, and fear of being bullied) were all examined. Odds ratios (ORs) adjusted for covariates were calculated for the four bullying-related constructs (bullying witness, bullying involvement, bystander intervention, and reactions to being bullied) using structural family factors.

Results

The result showed that all demographic household characteristics were associated with bullying at school except for being from a single-child family. Adolescents from rural families witnessed more bullying incidents than those from local families (OR = 1.35, 95% CI: [1.09, 1.68]). Adolescents who come from migrant families (OR = 1.12, 95% CI: [1.07, 1.43]) with a rural hukou (OR = 1.31, 95% CI: [1.00, 1.74]) and low parental education levels (OR = 1.42, 95% CI: [1.01, 2.57]) were more likely to be bullies. Adolescents who came from migrant families (OR = 1.37, 95% CI: [1.03, 1.82]), with low maternal education levels (OR = 1.42, 95% CI: [1.06, 1.91]) engaged in more negative bystander intervention behaviors. Furthermore, adolescents with less educated mothers experienced a higher fear of being bullied (never versus sometimes: OR = 1.33, 95% CI: [1.00, 1.85]; never versus usually OR = 1.39, 95% CI: [1.01, 1.20]).

Conclusions

A systematic examination of the relationship between school bullying and demographic household characteristics may be used to inform school policies on bullying, such as training management on the importance of paying attention to adolescents from disadvantage household backgrounds. Identifying demographic factors that may predict bullying can also be used to prevent individuals from becoming involved in bullying and reduce the related negative consequences from being bullied.

Association of health-risk behaviors and depressive symptoms and anxiety symptoms: a school-based sample of Chinese adolescents

Background Depressive symptoms and anxiety symptoms of adolescents not only affect youth but also have wide-ranging impacts on the health of adults. The study was carried out to determine the epidemiological characteristics of depressive symptoms and anxiety symptoms and the associations between the two and health-risk behaviors in Chinese adolescents. Methods Participants were recruited from the junior and senior high schools in China. Data were collected by self-designed questionnaires. The questionnaires included questions about demographic characteristics, depressive symptom scales, anxiety symptom scales and nine categories of health-risk behaviors. Descriptive analysis and binary logistic regression were performed by SPSS 21.0 software. Results There were 4.4% of the participants with depressive symptoms. Approximately 32.0% of the participants had anxiety symptoms. Girls and general senior school students were risk factors for depressive symptoms and anxiety symptoms. Multiple health-risk behaviors were associated with depressive symptoms and anxiety symptoms in Chinese adolescents. Conclusion Depressive symptoms and anxiety symptoms were prevalent in Chinese adolescents. Their distribution was affected by certain health-risk behaviors. Multiple health-risk behaviors were associated with depressive symptoms and anxiety symptoms in Chinese adolescents.

Relationships between family functioning, parenting and peer victimization in adolescent depression: A cross-sectional study

OBJECTIVE

Major depressive disorder (MDD) in adolescence is a prevalent mental health problem with a complex etiology and a rising incidence. The aim of the study investigated functioning of family, attitudes of parents, and peer victimization in adolescents with MDD and to compare those with healthy adolescents.

METHODS

The study was designed as a multi-center, cross-sectional, case-control study. 98 adolescents diagnosed with MDD and 99 healthy controls were recruited for the study. Beck depression inventory, parental attitude research instrument (PARI) tool, family assessment device (FAD), and multidimensional peer victimization scale (MPVS) were applied to all participants. Descriptive, correlational, and bivariate group comparisons were used in analyses.

RESULTS

The average ages of adolescents with MDD and control adolescents were 14.7 (S.D.=1.5) and 15.0 (S.D.=1.6) years, respectively. Females formed 74.5% of youth with MDD (vs. 70.3% of controls). The groups were similar in terms of socio-demographic features (all p>0.05). Adolescents with MDD had significantly elevated scores in FAD subscales except problem solving, PARI rejection of homemaking, marital conflict, and authoritarian subscales, and all MPVS subscales. Adolescents with MDD also displayed significant positive correlations between all MPVS subscales and FAD subscales except FAD problem-solving.

CONCLUSION

This cross-sectional, multi-center study suggests that family dysfunction and peer victimization may be higher in youth with MDD. Although cross-sectional design precludes evaluation of causality, it may be prudent to evaluate family functions as well as peer victimization of depressed youth.

Predictors of One-Year Change in How Youth Perceive Their Weight

Overall, perceptions of being at "about the right weight" appear advantageous for youth physical and mental health, regardless of BMI classification, whereas perceptions at either extreme (overweight or underweight) may negatively impact health behaviours and mental health. Instead of considering weight misperceptions as problematic, some researchers have proposed that underestimations of weight status may offer resiliency among individuals with overweight or obesity. Promoting "about right" WPs and preventing change to overweight or underweight perceptions may offer an effective public health strategy for supporting youth health over time. However, limited prospective evidence exists on factors that shape perceptions of weight status over time. The current study examined modifiable predictors of one-year change in weight perception among youths. We used 2-year linked data of 18,112 grade 9-12 students from Year 3 (Y₃:2014-2015) and Year 4 (Y₄:2015-2016) of the COMPASS study. Generalized Estimating Equation models tested screen use, physical activity, and bullying victimization as predictors of change from perceptions of "about the right weight" to "overweight" or "underweight" perceptions, adjusting for Y₃ covariates (body mass index, ethnicity, and grade) and school cluster. Results support the value of team sports among females and resistance exercise among males as protective against changes to overweight or underweight perceptions over one year. Also, various forms of bullying victimization predicted overweight perceptions in males and females. Watching TV/movies or messaging/texting for over 2 hours/day was associated with overweight and underweight perceptions, respectively, in females only. Playing video/computer games for over 2 hours/day was associated with overweight perceptions in males and underweight perceptions in females. Findings support the potential of bullying prevention, limiting certain screen use, and supporting engagement in team sports for females and resistance exercise for males as strategies to maintain perceptions of being at "about the right weight."

Associations between self-efficacy, bullying and health-related quality of life in a school sample of adolescents: a cross-sectional study

Background

To better understand health-related quality of life (HRQOL) in adolescents, it is important to gain knowledge about factors associated with HRQOL. Being involved in bullying is a significant threat to health, and social and psychological well-being; further, such problems can last into adulthood. The aim of this study was to explore the role of general self-efficacy (GSE) and bullying in relation to HRQOL. We specifically sought to study the prevalence of bullying, as well as the associations between both bullying and self-efficacy and HRQOL in a sample of adolescents.

Methods

This was a cross-sectional study of 723 adolescents (12–18 years) attending schools selected using randomized cluster sampling. HRQOL was measured using the KIDSCREEN-52, self-efficacy was measured with the GSE scale, and bullying was measured using the two global questions from the Olweus bullying questionnaire. Multiple regression analyses were performed to explore how being bullied, bullying, and GSE were associated with variations in self-reported HRQOL.

Results

Of the 723 adolescents, 13% reported being bullied; there were no gender differences within this finding. However, more boys than girls reported that they had bullied others. Both being bullied, and bullying others, were associated with lower HRQOL; however, being bullied was associated with the lowest scores. Higher self-efficacy was associated with better HRQOL. Self-efficacy contributed significantly to predicting variation in HRQOL.

Conclusions

Being involved in bullying, as a victim or a bully, is associated with lower HRQOL. The association between GSE and HRQOL indicates that self-efficacy might be a resource for increasing HRQOL among adolescents. Our findings highlight the importance of targeting self-efficacy beliefs as an intervention strategy to improve GSE and HRQOL in adolescents involved in bullying.

Bullying in School: Importance of and Challenges Involved in Talking to the School Nurse

Bullying has negative consequences for health and quality of life of students. This study is part of a pilot project, “School Health,” which included a web-based questionnaire completed by students before a consultation with the school nurse. The aim of this study was to explore how students experience answering questions about bullying before an individual consultation and how they talk about bullying with the school nurse. This study had qualitative design with individual and focus group interviews and involved 38 students aged 13–14 years, both boys and girls, from three schools. Data were analyzed according to Kvale’s three levels of interpretation within a phenomenological and hermeneutic perspective. The students found it difficult to report being bullied. They expressed confidence in the school nurse and liked talking with her. Some complained about the school environment and reported that having a friend was important.

Socioeconomic trends in school bullying among Finnish adolescents from 2000 to 2015

Bullying at school has far-reaching impacts on adolescent well-being and health. The aim of this study was to examine trends in bullying at school according to socioeconomic adversities among Finnish adolescents from 2000 to 2015. A population-based school survey was conducted biennially among 14-16-year-old Finns between 2000 and 2015 (n = 761,278). Distributions for bullying, being bullied and socioeconomic adversities were calculated. Associations between bullying involvement, time and socioeconomic adversities were studied using binomial logistic regression with results shown by odds ratios with 95% confidence intervals. At the population level, the likelihoods of bullying and being bullied varied only slightly between 2000 and 2015. Bullying and being bullied were associated with socioeconomic adversities (low parental education, not living with both parents and parental unemployment in the past year). Unlike in the general population, the likelihoods of bullying and being bullied increased markedly among adolescents with most socioeconomic adversities. The increased socioeconomic differences in bullying involvement observed in this study add to the mounting evidence of polarization of adolescent health and well-being. Socioeconomic adversities should be considered in the prevention of bullying at school. In addition, socio-political measures are needed to decrease socioeconomic inequalities among Finnish adolescents.

National data study showed that adolescents living in poorer households and with one parent were more likely to be bullied

Aim

The aim of this study was to assess whether sociodemographic household characteristics were associated with which Swedish adolescents were more likely to be bullied.

Methods

The data were derived from the Swedish Living Conditions Survey and its child supplements from the survey years 2008–2011. The analyses included information on 3951 adolescents aged 10–18 years. Exposure to bullying was reported by adolescents, and information on sociodemographic household characteristics was reported by parents and obtained from official registers. Binary logistic regression was used to analyse the data.

Results

Adolescents were more likely to be bullied if they lived in households with no cash margin, defined as the ability to pay an unexpected bill of 8000 Swedish Kronor or about 800 Euros, and if they lived with just one custodial parent. In the unadjusted analyses, elevated risks were identified if adolescents lived in working class households and had unemployed and foreign‐born parents. However, these associations were at least partly accounted for by other sociodemographic household characteristics, in particular the lack of a cash margin.

Conclusion

This study showed that Swedish adolescents living in households with more limited financial resources had an increased risk of being bullied, supporting results from previous international research.

Saúde do escolar: uma revisão integrativa sobre família e bullying

Resumo O “bullying” é um problema de saúde pública e, nesta revisão, objetivou-se avaliar a relação entre o contexto familiar e a ocorrência do fenômeno. Sua contribuição original é a abordagem ampliada sobre esse tipo de violência. Utilizou-se a estratégia SPIDER na construção do estudo que foi guiado pela questão norteadora: qual o papel da família no desenvolvimento, manutenção e prevenção do “bullying”? Foram consultadas as bases PsycInfo e Lilacs, e a biblioteca virtual SciELO, a partir dos cruzamentos 1. “bullying and Family” e 2. “bullying and parents”, e seus correlatos em português e espanhol. A qualidade metodológica dos estudos foi avaliada segundo critérios de nível de evidência. Foram incluídos 27 artigos, publicados entre 2009 e 2013, nos idiomas inglês, espanhol e português, com prevalência de evidências entre forte e moderada. Nos estudos, o delineamento predominante foi o transversal e a maioria não indicou o referencial teórico adotado. Aspectos qualitativos do contexto familiar, características sociodemográficas e experiências de violência em casa foram associados com o envolvimento de escolares em situações de “bullying”. Revelou-se que o “bullying” requer intervenções intersetoriais e são estimuladas investigações com foco não apenas nas características individuais dos estudantes, mas também nos contextos.

Prevalence and patterns of traditional bullying victimization and cyber-teasing among college population in Spain

BACKGROUND

Traditional bullying victimization and the growing number of cyber-teasing victims during the last decade is a major public health concern. The objective of this study was to examine the relationship between students' experiences of traditional bullying victimization and cyber-teasing and the sociodemographic characteristics of a sample composed of college students in Spain.

METHODS

In the fall of 2014, 543 sixth-grade students from southeast Spain completed an anonymous survey on their experience of both kinds of to ascertain any relationship with sociodemographic characteristics, including gender, nationality, economic problems, family conflicts and alcohol and cannabis use.

RESULTS

A total of 62.2% of the students reported to having suffered traditional bullying victimization and 52.7% reported that they had been subject to cyber-teasing. 40.7% of participants had been victims of traditional bullying victimization and cyber-teasing in the past 12 months. Most (65.7%) of the victims were at the same time cyber-teasing victims; 77.6% of cyber-teasing victims were also victimized in a different manner. Traditional bullying victimization was higher among boys than among girls, while female students were more likely to have been subjected to cyber-teasing than male students. The characteristics that most heavily influenced suffering traditional bullying victimization were economic problems, family conflicts and cannabis use.

CONCLUSIONS

Our findings confirm overlapping results in the risk factors that influence suffering both traditional bullying victimization and cyber-teasing: there was a strong influence of certain sociodemographic and individual characteristics of the college population, suggesting that specific policies are necessary to improve college students' environment in Spain.

The association between bullying-related behaviours and subjective health complaints in late adolescence: cross-sectional study in Greece

BACKGROUND

Bullying is quite prevalent in the school setting and has been associated with several subjective health complaints such as headache, backache, abdominal pain, dizziness, fatigue and sleep problems. The aim of the present study was to investigate the association between bullying and subjective health complaints in a sample of Greek adolescents taking into account the presence of psychiatric morbidity.

METHODS

A stratified random sample of 2427 adolescents aged 16-18 years old and attending senior high schools were randomly selected for a computerized interview. Subjective health complaints were assessed using a symptom checklist used in the context of a previous World Health Organization study and relevant sections of the revised Clinical Interview Schedule (CIS-R). The latter was also used for the assessment of psychiatric morbidity. Bullying was assessed with the revised Olweus bully/victim questionnaire. A series of logistic regression models were used to investigate the association between bullying and subjective health complaints.

RESULTS

Victims of bullying were more likely to report backache (Odds Ratio [OR] = 1.92, 95% CI: 1.01-3.67), dizziness (OR = 2.83, 95% CI: 1.11-7.22) and fatigue (OR = 0.41, 95% CI: 0.19-0.86), independently of the presence of psychiatric morbidity. In addition bullying perpetrators were more likely to report backache (OR = 3.49, 95% CI: 1.49-8.18). It is worth noting that sleep problems and abdominal pain were also associated with being bullied and fatigue with bullying perpetration but these associations were all attenuated after adjustment for psychiatric morbidity.

CONCLUSIONS

Strong associations between bullying in schools and subjective health complaints among a sample of Greek students aged 16-18 years have been observed. The exact nature of these associations should be investigated in future longitudinal studies.

Socioeconomic status and bullying: a meta-analysis

We examined whether socioeconomic status (SES) could be used to identify which schools or children are at greatest risk of bullying, which can adversely affect children's health and life. We conducted a review of published literature on school bullying and SES. We identified 28 studies that reported an association between roles in school bullying (victim, bully, and bully-victim) and measures of SES. Random effects models showed SES was weakly related to bullying roles. Adjusting for publication bias, victims (odds ratio [OR] = 1.40; 95% confidence interval [CI] = 1.24, 1.58) and bully-victims (OR = 1.54; 95% CI = 1.36, 1.74) were more likely to come from low socioeconomic households. Bullies (OR = 0.98; 95% CI = 0.97, 0.99) and victims (OR = 0.95; 95% CI = 0.94, 0.97) were slightly less likely to come from high socioeconomic backgrounds. SES provides little guidance for targeted intervention, and all schools and children, not just those with more socioeconomic deprivation, should be targeted to reduce the adverse effects of bullying.

Prevalence and characteristics of victims and perpetrators of bullying

OBJECTIVE

To determine the prevalence of bullying (victims and perpetrators) in a representative sample of sixth graders from schools located in the city of Caxias do Sul, RS, Brazil and to determine possible associations with maternal education, socioeconomic level, sedentary habits, nutritional status, dissatisfaction with body image, gender, and age.

METHODS

This was a school-based epidemiological study. The target population consisted of sixth graders (11-14 years). A self-administered questionnaire and anthropometric measurements of weight and height were used for the assessment of nutritional status. Bullying was assessed through the Kidscape questionnaire, and body image through the Body Shape Questionnaire. Descriptive statistics and bivariate and multivariate analyses were used.

RESULTS

1,230 schoolchildren were evaluated, and the prevalences of victims and perpetrators of bullying were 10.2% and 7.1%, respectively. Those dissatisfied with their body image were three times more likely to be victims of bullying (PR=3.24; CI=1.99- 5.28), and almost twice as likely to be aggressors (PR=1.98; CI=1.53-3.73) than those who were satisfied. Schoolchildren with sedentary habits (more than three hours a day) were 55% more likely to be victims of bullying (PR=1.55; CI=1.01- 2.36) and more than twice as likely (PR=2.42; CI=1.47-3.97) to be aggressors. Boys were more than twice as likely (PR=2.45; CI=1.42-4.24) to be aggressors.

CONCLUSIONS

Body image and sedentary habits were associated with victims and perpetrators, and male gender was more prevalent among the perpetrators of bullying.
